BUFFER FOB. nxrnosrvn SHELLS.

Be itfknownthat I, JoHN'LaoxNnn, citizenof the United-States, and aresi'dent of the city of New York, Flushing, borough of Queens, inthe county of Queens and 5 State of New York, have 'invented a new and Improved Buffer for ExplosivefShells,

of whioh the following is av full, clear, and

' exact description. l

The object of the invention is to provide anew and'improved flexible and pliable arti cle ofmanufacture for use, for instance, as a bufi'er, gromet or a fender on explosive shells to permit of safely stacking such shells and l prevent it accidental premature explosions thereof- Another object is to permit of using the'article 'of manufacture for vari- 'ous purposes, the article having the desired resilient and pliable qualities. Another object is to permit or: providing an article of this flexible and pliable character, which p is "cheap to manufacture, exceedingly du-' '7 rable and not liable to open up or break" when in use. 7

- With these and other objects in view, the inventionconsists of certain novel features of construction, as hereinafter shown and def scribed and then specifically pointed out in the claim.

' For the purpose of illustrating my inven tion, I have shown in the accompanying drawings one form thereof which is at pres ent preferred by me, since the same will be i found in, practice to give satisfactory and '35 reliable results,- although it is to be underv stoodthat the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organizatlon of these instru- -mentalities as herein shown and described,

Aipracticalrembodiment of the invention is represented in the accompanying draw ings' forming apart of this specification, in

71 which similar characters of reference indica te corresponding parts in all the views.

Figure 1 is a perspective view of a tubular piece of knitted fabric forming the blank for making the art1cle of manufacture' v 2 is a sectional side elevation of the same partly rolled up;

' Specification of Letters Patent. Patented Feb. 1920. Application filed September as, 1918." Serial No. 256,675.

Fig. 3 is a perspective view of the article of manufacture; i

J F 1g. 1 is an enlarged cross section of the same on the line 4l1 of Fig. 3; and

h Fig. 5 is an enlarged side elevation show-' ing the means for fastening the edge of the p v outermost layer to the body.

The blank 10 from whichthe article of manufacture is made isa tubular piece of knitted textile fabric of an interior diame ter corresponding to the inner diameter of the article to be 'made. The blank l0 is rolled up outwardly beginning at one edge to provide an annular body 11 formed of superimposed annular layers of the textile material, as plainly indicated in Figs 2, 3

noticed that the annular. body 11 is cylindrical in cross section and'as it is formed of superimposed layers of a knitted textile fabric having its edge secured by a tying cord which is reeved through the loops on the outer edge of the body and'juxtaposed loops on the adjacent convolution of the roll, it is evident that the desired resiliency is had not only throughout the body but through-its pliable fastening means and the.

body and its fastening means being flexible and pliable throughout can somewhat stretch in the direction of its length to insure a close fit on a shell or other article on which it is to be used as-a buffer, fender or gromet. It will further be noticed that the article can also be used for various purposes, and I do not limit myself'to any particular use that may be made of the article;

Although a' lmittedblank is prepared I do not limit myself to such textile material as a braided tubular blank or a loosely woven tubular blank may be used. Al-

though the blank is shown and described as rolled up outwardly it is' evident it may be rolled up inwardly, but in this case the diameter of. the tubular blank must be in convolution of the roll;

essential for the purposes intended that not only t-h'ebod'y of the device 'fiexiblel and" pliable but that the fastening means which secures the juxtaposed edges be equally flexible and pliable and to this 'endjIiemlploy the tying cord-7'13, which is reeved through the loops on the: outer edge :oi the body and juxtaposed loopson the adjacent the completed article is renderedveiyjilexhv area, so that when the device isLeIIiPloyod 01' the other plurposes' intended, its inherentfiexi- I entiated from the through loops therein but such a device is I bleand pliable qualitiesthroughont its en-' tire area will render it particularly apbefore rolling is treated Withadhesive ,ma-' terial, so 't'hat the foldsorln eefing portions stick oi' adhere together; so asitlo form one concrete mass, 1whieh Qbv'ibuslyI not possess thepliability and fiexibji'lity'of my device.)
